The method disclosed by the invention adopts a composition with an effect of removing the colored mordant on the ground color of the printed fabric, and prints the removal color paste on the white ground part without patterns to obtain the natural dye printed fabric with white ground color; the aftertreatment technology is the same as the conventional printing technology, and additional process is not needed; and meanwhile, the grade and added value of the natural dye printed fabric are increased.
Description
Technical field
The present invention relates to the fabrics printing and dyeing process technology, particularly a kind of white method of mordant on the ground of natural dye PRINTED FABRIC of removing belongs to the textile printing and dyeing processing technique field.
Background technology
Textiles must adopt different dyestuffs to dye or the stamp processing in order to obtain the pattern of gay colours and glamour.The developing into us and bring convenience efficiently dyeing and printing process technology and the gorgeous world of synthetic dyestuffs, yet the high chemical stability of synthetic dyestuffs and low biodegradability increased the treatment of dyeing wastewater difficulty, increase the weight of pollution that ecological environment is caused, and synthetic dyestuffs also show especially day by day to the harm of human body.Natural dye and Environmental compatibility are good, and be biodegradable and nontoxic, and skin without anaphylaxis and carcinogenic, is met the ecological requirement of textiles, has obvious advantage aspect the high-grade ecological textile of exploitation.
In recent years, natural dye is very extensive for the correlative study of textile dyeing.Because the molecular weight of natural dye, hydrophobic structure is little, with interfibrous Van der Waals force and hydrophobicity effect all a little less than, the affinity to fiber during natural dye dying is more much lower than synthetic dyestuffs, in addition, the molar absorption coefficient of dyestuff is also smaller.Therefore, adopt natural dye dying often to use mordant to process or other processing methods, to increase the dye-uptake of dyestuff on fiber.Mainly contain the salt of the metal ions such as copper, iron, aluminium as the mordant of natural dye, the method for mordant dyeing is divided into first matchmaker and rear matchmaker processes.It generally is with behind a certain amount of mordant solution-treated fabric that the matchmaker of elder generation processes, and dyes with natural dye again; It is that fabric passes through first natural dye dying that rear matchmaker processes, and then processes with certain density mordant.Metal ion in the mordant can with dye molecule in hydroxyl, carbonyl etc. form complex, can also with fiber in hydroxyl, amino and carbonyl form the complex thing, between dyestuff and fiber, form the connection bridge by metal ion, increased on the one hand the dye-uptake of dyestuff on fiber; Strengthened on the other hand the combination of dyestuff and fiber, be conducive to improve every fastness of DYED FABRICS, in addition, the metal ion in the complex can promote the pi-electron in the dyestuff conjugated system to flow, and can produce hyperchromic effect.
Stamp is to make dyestuff form the process of the floral designs with different color at fabric.The stamp processing of synthetic dyestuffs is very general.If but adopt the natural dye stamp how to carry out the problem that mordant dyeing is processed with regard to existing.
Document (S. Kale, S. Naik, R. Gaikwad. Mordant Printed Cotton Fabric Dyed in Natural Dye[J]. Man-made Textiles in India, 2009 (8): 279-281.) reported with the mill base that contains metal salt mordant and print at real silk, the method that dyes with the English walnut pigment again, the deficiency of its existence is that the ground color part that does not print mordant has also simultaneously been caught color, just ground colour is different with the pattern color, can not obtain ground colour and be the PRINTED FABRIC of white.Document (M.Gablot, N.Papni, N.Fatima et a1. Printing with natural dyes [J] .International Dyer, 2005 (9): 18-20.) reported pre-mordant dyeing and the synchronous two kinds of methods of mordant dyeing of adopting, during synchronously mordant dyeing, mordant and dyestuff are directly put into mill base, fabric is carried out stamp, the deficiency of this method is the dyestuff in the mill base, the coordination combination may occur between mordant and the printing gum, to cause the unstable of mill base on the one hand, can affect on the other hand dyestuff to the transfer of fiber, and then cause tinctorial yield to descend.The method of pre-mordant dyeing is to want the fabric of stamp to carry out the mordant dyeing processing with a certain amount of mordant solution integral body first, then carries out stamp by pattern, and stability of pigment paste and the reappearance of this method are relatively good.But the deficiency of this method is most of metal ions that are used for mordant dyeing exists certain color, can cause the color that stay white ground color part to embody metal ion, can not obtain equally ground colour and be the PRINTED FABRIC of white.As from the foregoing, natural dye is used for the problem that printing in textiles also exists needs to solve.
Summary of the invention
The object of the invention is to overcome the deficiency that prior art exists, provide a kind of and can effectively remove the white mordant on the ground of natural dye PRINTED FABRIC, improve the mordant of natural dye mordant dyeing printing quality and remove mill base and application thereof.
Technical scheme of the present invention provides a kind of white method of mordant on the ground of natural dye PRINTED FABRIC of removing, and comprises the steps:
(1) by weight percentage, with the former paste 50～80% of stamp, oxalic acid 0.3～1.0%, urea 2～5%, chelated dispersants maleic acid-acrylic acid copolymer 0.5～2.5%, nonionic penetrant 0.01～0.1%, water 15～40% mixes, and the preparation mordant is removed mill base;
(2) with silk or wool fabric after the pre-mordant dyeing of metal salt mordant is processed, according to required decalcomania natural dye impressing pattern, print mordant in the white ground of PRINTED FABRIC part and remove mill base, again routinely printing technology dry, decatize, washing, drying and processing, obtain a kind of natural dye PRINTED FABRIC.
Described nonionic penetrant is a kind of among fatty alcohol polyethenoxy ether class non-ionic surface active agent JFC or the AEO9.
The former paste of described stamp is a kind of of synthetic gum tragacanth paste, cluster bean adhesive paste, or both mixing are stuck with paste.
Described metal salt mordant is the compound of divalent iron salt or trivalent iron salt.
Compared with prior art, advantage of the present invention is:
1, the present invention adopts the combination that coloured mordant on the PRINTED FABRIC ground colour is had the removal effect, by not having dapple this kind removal mill base that partly stamps in vain, obtaining ground colour is the natural dye PRINTED FABRIC of white, improves class and the surcharge of natural dye PRINTED FABRIC.
